<p align=center><b>Release 4.2: DB-&gt;del</b></p>
<p>In previous releases, the C++ <a href="../../api_cxx/db_del.html">Db::del</a> and Java Db.delete
methods threw exceptions encapsulating the <a href="../../ref/program/errorret.html#DB_KEYEMPTY">DB_KEYEMPTY</a> error in
some cases when called on Queue and Recno databases.  Unfortunately,
this was undocumented behavior.</p>
<p>For consistency with the other Berkeley DB methods that handle
<a href="../../ref/program/errorret.html#DB_KEYEMPTY">DB_KEYEMPTY</a>, this is no longer the case.  Applications calling
the <a href="../../api_cxx/db_del.html">Db::del</a> or Db.delete methods on Queue or Recno databases,
and handling the <a href="../../ref/program/errorret.html#DB_KEYEMPTY">DB_KEYEMPTY</a> exception specially, should be
modified to check for a return value of <a href="../../ref/program/errorret.html#DB_KEYEMPTY">DB_KEYEMPTY</a> instead.</p>
